LaserJet 8500: a huge awesome ancient laser printer

Filed under: Random Thoughts — Dr. Lawlor @ 8:52 pm

At a surplus auction today, I picked up an Apple LaserJet 8500, a 60 pound black and white laser printer from the 1990’s.  Why did I bother buying such an ancient beast?

It can feed huge 13 x 19 inch paper!  I often do robot design work in CAD, then laser print a template to glue onto steel, plywood, plastic sheet, or whatever material for further drilling, cutting, and machining.  This means the size of my parts is limited by the size of my printer, so a big printer lets me build bigger parts more easily.

Anyway, the hard part was getting the printer’s IP address.  Once you have the original IP, you can reconfigure it via telnet (it will make you set a password), and then send it Postscript files via the JetDirect (9100) network port.  All you need is the LaserJet 8500 PPD file, version 1.2–link is plain text that I had to unpack from Apple’s ancient classic Mac smi.bin file using the BasiliskII emulator.
